1 ALLANSON ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Conwy local authority area over time, sourced from the HPI. The three 1 ALLANSON ROAD sales between August 1997 and October 2017 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the March 2013 sale was for 140% above the HPI. So the extrapolation line tracks at 140% above the HPI over time, until the October 2017 sale, where it falls to 131% above the HPI. The line then continues to track at 131% above the HPI.

What might 1 ALLANSON ROAD be worth now?

1 ALLANSON ROAD might now be worth an estimated £704,949.

This is based on house price inflation of 36.9%, between October 2017 and February 2025, for detached houses, in the Conwy local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 36.9% inflationary increase is applied to the most recent sale price for 1 ALLANSON ROAD of £515,000 on 11th October 2017. For the value to have increased from £515,000 to £704,949 over the eight years and eight months to February 2025, the following assumptions must hold true:

• The value of 1 ALLANSON ROAD has moved in line with the HPI for detached houses in the Conwy local authority area.
• The October 2017 sale price of £515,000 represented a fair market value for the property.
• The size, condition, and specification of 1 ALLANSON ROAD has not materially changed since October 2017.
